Fusarium graminearum (F. graminearum) in maize poses a threat to grain security. Current non-destructive detection methods face limited practical applications in grain quality detection. This study aims to understand the optical properties and volatileomics of F. graminearum-contaminated maize. Specifically, the transmission and reflection spectra...

BACKGROUND Lactose is a critical factor in the quality of milk and dairy products. Achieving high accuracy and rapid detection of lactose content in cow's milk remains a challenge. Dielectric spectroscopy has emerged as a promising tool for detecting food components. We explored the effect of lactose content on the dielectric spectra of cow's milk...

The nonhomogeneity of bovine colostrum leads to strong scattering effects for electromagnetic waves, which affects the application of electromagnetic spectroscopy in detecting colostrum. This work aimed to compare the performance of near-infrared spectroscopy (NIRS) and dielectric spectroscopy (DS) in quantitatively predicting the content of mature...

BACKGROUND The rapid and accurate identification of colostrum, a strong non‐homogeneous food, remains a challenge. In the present study, the dielectric spectra including the dielectric constant (ε′) and loss factor (ε″) of 154 colostrum samples adulterated with 0–50% mature milk were measured from 20 to 4500 MHz. RESULTS The results showed that th...

Identifying the adulterated bovine colostrum is helpful to guarantee the quality of colostrum products and protect the legitimate rights of consumers. Near-infrared (NIR) spectroscopy technology has been proved to be able to predict the main compositions of milk, but the scattering of particles in colostrum has big effect on obtained NIR spectra. T...
